i did make one a while back and for what it was it was pretty awesome... nothing like this but the concept was there... the only problem i had with mine is the same as anyone running a stock diff... it would bind under hard left hand turns... i looked everywhere for a slim enough bearing to stick in there but found nothing... i tried shimming but it would still bind when i got to the stronger mottors... especially in the sweeper... this design by Phil will not have these problems... and with mine i had to use different weight grease to slow down the diff... phil has incorporated the smae tension design as a standard ball diff... you will be able to control the speed of the gears by loosening or tightening the pressure washer... its a pretty amazing design and concept...

Can someone explain why they would want a gear diff rather than a ball diff? I don't get it?

JuniorWKR
2012.01.18, 02:13 PM
imo... you would benefit from a gear diff when running higher turn motors such as 80t or 70t stock class racing... the reason for this is the motors arent strong enough to spin the tires if there is traction so most of the times we just lock up our ball diffs to eliminate slip to pick up those precious tenths of a second every lap... the down side to this is when you lock up a ball diff you lose rotation cause it doesnt allow the ball diff to transition quickly through the infield... with a gear diff there is no chance of slip but it will always spin freely... allowing for greater rotation through the infield...

2012.01.18, 05:18 PM
Good explanation. :) I was actually going to use mine for Mod -- in 70t or 80t Stock the motors don't actually slip the diff so you can leave a ball diff super-loose (I sometimes even use harder rear tires) for turn-in steering and corner exit speeds and tire loads are lower so you won't "diff out" on exit.

In Mod though, super-loose diffs WILL diff out on exit, and tighter diffs hamper off-power turn in. The gear diff removes this compromise as it's loose off-power for turn-in, tight on-power for exit speed, and (an extra benefit) tight on-brake for braking stability. When I drove Grant's prototype, the forward drive on exit was huge. :) The strong locking effect and no-slip design makes the rear end slip out a little more, but at the same time the slip is predictable = more exit steering. The only conditions in which I wouldn't dare use a gear diff is if there's not enough rear traction to make a safety envelope for the increased steering all around.

JR, we got a taste of it last night in JT's car and it was amazing in 70T stock. The corner throttle was instant response especially through the carousel in full throttle without loosing composure! Also weights like nothing of 4 gram so can't weight to my hands of one.

If the diff works as good as it looks and I'm pretty sure it will, it will be worth the price whatever it is. Like already mentioned in this thread I think it will make an awesome stock class diff. And if PN is working on a AWD gear diff, that would be sssssssswwwwwweeeeeeeeeeeeeeetttttttt! :D Well apparently I posted right after PN did.:o that price is reasonable.

Whats wrong with the stock awd gear diff to need a metal version? Mod? Will the heavy duty version of the gear that they are coming out with for the buggy work on the awd?

Not sure I see why would need a new gear diff UNLESS its going to be sealed w/oil.

Same differential, isn't it? :confused:


Anyways, I picked up a new diff last night at Kenon and it's an engineering masterpiece. :) Fast too, as I expected, you get more steering because it's super-free AND more exit drive. But because of the instantaneous power delivery, you need either more rear traction as a safety envelope or to become a better driver with the throttle and keep the tail in check. With my old PN Radial 7's the grip was just not quite enough to be consistent. I have a set of surprisingly good Slick 8's left over that I'll try next time, and of course new Radial 7's would probably be just perfect with my tail-heavy GT-R.

I let Clement (top TCS driver and new Kenon regular!) borrow the gear diff at one point and slapped on some worn Radial 6's onto his MR02 (McLaren F1 shorttail). When I went to test-drive his car in between races, it was awesome! Even though it wasn't tuned to my driving style and I had to adapt, I was still well able to chase down and pass the other fast guys on the track because there was just so much turn-in and corner speed.

I'll be putting the gear diff back into my car before the next race and actually mounting up new tires so I can give the diff a fair trial on my infamously sensitive car setup. Having driven Clement's car after tweaking it I think this diff has huge potential! :)

Here is just little impression of this new Gear Diff with optional 52 teeth Spur from an average driver's point of view in going through 4 packs tonight by burning up a set of Kyosho 30's & 20's from a PN 70T at 94 mm chassis.
Right away, you feel the instant power on acceleration and very linear though out the packs. There is so much corner steering especially on high speed sweepers that you can hold throttle in carousel without lifting.
Only thing about this gear diff is that it does keep you on the edge because there is no give in any slippage which means you really have to have high grip rear tires to keep your car inline. As rear tires wear and traction start to fade, you must have good enough throttle control because you can't just lift off too violently at turn ins or you will kick the rear end out in over steer. In the butt dyno, your car does feel somewhat faster and I did achieved few personal best laps faster then previous ball diff. At the end, switched back to a light weight Reflex/PN combo Ball diff in comparing, you can feel the give in slippage at cornering that gives your room for error which this Gear Diff will not. To sum it up, I like it a lot in precision craft and function plus ease of changing Spur gear but it will take more time to adjust one's driving style since it is all power or nothing!

Simplely 1st. loosen the back O-Ring tensioner to release load from E-Clip side. Then remove E-Clip. Next take off Bearing Hubs which now 3 worm gears are expose. You can retract all 3 worm gears with center pin towards drive shaft since it is the 3 worm gears center pin holding the Spur Gear down. Now lift off the OEM 53 teeth Spur Gear and replace it with 52 teeth or whatever you have as your option. Now push back up the 3 worm gears and their center pin will lock your new Spur Gear back in place. Final step is reinstall the Bearing Hub & E-Clip. On track, Adjust O-Ring tensioner to give you somewhat tiny back lash between all the gears to either just lessen or more instant throttle responses. Good Luck!

Eddie, not need take off the E-clip.

Changing Spur Gear Ratio

1. Loosen Tension Nut to separate side gears.

2. Allow spider gear pins to recess into carrier. Depress with screw driver if necessary as shown by arrows.

3. Remove spur gear.

4. Installation is reverse of removal

Installed today. Very impressed with the build quality and smooth-ness out of the pack. Felt great in my hands and did what is was supposed to do on the track (only ran 20-30 laps).

I don't know if I'll take this apart til Monday. I ran quite a few laps with this on a set up today. I think I've got the whole package more dialed now. Tomorrow will tell with some timed runs. Our track seems to get rather dirty quickly, so I am anxious to see how clean it stays, and how it fares against RCP.

Raced it in our Friday Night Club Racing & I think is a winner!
Gotta tell ya, I did my personal best hot laps in all 3 qualifier and most laps done ever in A-main from the same layout for past 4 weeks. Power delivery was instant and cornering speed were up there . The turn in was a breeze and held so planted through at 180R carousel turn. All this was done in our Stock Spec series with PN70T & Kyosho 30's & 20's.

i was up in the air, mostly due to price...but when I was told about the limited availability, that diff somehow ended up in my car. LOL

All I can say is OMG tons of steering... especially when using the HSV body. In my mod I have tons of exit steering...got that fixed, and tonight I will try with some new rubber in the rear.

That diff is extremely smooth...compared to my diffs because I suck at building diffs.

Does the adjusting on this actually work? Like say, a ball diff or normal diff with different oils, or is it "something else"?

It works. :) The gear preloading just puts some pressure on the gears themselves, so it's like tightening a ball diff. Somehow, PN got the gears machined just right so the diff is still smooth even after you tighten the nut down. :eek:

My impressions of the diff after trying it yesterday are that 1) it kicks major amounts of arse for 80t and 2) there's not enough grip to use it in Mod. I bought a PN 39t to see if the torque would overwhelm the rear end on exit and the answer is "Yes. Yes it does." I'll try again with the smoother PN 33t and a more understeer-biased setup and see if I can somehow make use of the gear diff's excellent corner speed. Otherwise, it's back to the ball diff for Mod. :)

I ran it yesterday in a event, and all I can say is I like it, and I need another one :D Over all, I turned a couple of hotter laps, and went a extra lap in the main with the VDS set up I was running, but that car was about 4g lighter, and everything in that race went my way.

The diff performs as described here. A quick pro/con list:
PRO:
Light weight
Instant throttle feel
Super free off power
Very consistent
Maintenance free

CON:
The gear side nut will tighten the gear mesh inside (no different than ball diff)
It rips so hard out of the corner, I spun two brand new pinions off :D A little super glue covered that :D

This is all still preliminary. I installed the diff Thursday night, practiced and tuned the car Friday, and raced an event Saturday. Longevity is going to be key, but cannot be determined yet. The diff setting stayed constant, and the diff stayed relatively clean.

josyskunk
2012.01.30, 03:52 AM
I am thinking using some kind of lube to make the action smoother. But I don't think heavy oil is a good direction because I want the diff as loose as possible. I am thinking the kingpin oil from Kyosho or "DuPont Teflon Multi-Use Dry Wax Lubricant"

what do you guys think?

Me too, works great. My only real issue was that I spilled some on the threaded part of the axle I guess, so the Delrin adjusting nut was shifting around a little bit until I threadlocked it.

FWIW, I run the diff fairly loose. No real preload on the gears, I'm maintaining about 0.1mm of slop in the gearset so the spur can actually tilt back and forth almost 0.5mm at its furthest point (edge of the spur teeth). Any tighter and I have big issues planting the rear end on corner exit. As it stands I'm letting the rear end "diff out" slightly, which is better than losing traction altogether and spinning the car into the wall. I'm looking forward to playing with it again this coming weekend. :)

Still running it dry, still no maintenance done, just driving it, and driving it hard! Had a club race last night to run the diff for the second time under race scenario. The car was very consistent. I set TQ in every round until the last where I got jumped by Chad, who is also now running the same diff. With the diff in his car he managed to beat the lap record for the new layout, which had pan cars running on this weekend. His car is blazing, but for the first time in months I am able to match pace with him.

What about the shaft? I can't seem to find a replacement shaft for it. Is it the same as the pn ball diff shaft, or am I just screwed iwhen I bend this one. I tend to go through them pretty quick.
I'm also assuming that the normal 64p pinions will also work with this?

color01
2012.02.02, 07:51 PM
The gear diff has its own proprietary shaft, so if Philip is out of stock then you're a bit out of luck. :( On the other hand, the hard-anodized 7075 aluminum shaft is pretty darn tough -- if Grant and I can't bend it with our crashing I don't think it's going to be easy. ;)

Normal 64p pinions work fine with the spur -- the machined ones are even smoother although a bit expensive and a tad heavier.

bevo
2012.02.02, 10:28 PM
Thanks, I just found the 64p in stock. I ordered the other earlier and requested it be canceled, so hopefully I don't end up with both the 64 and regular one. What's the # for the shaft for it?

I can really go much faster than any other racer on the track and reach the fastest lap on the track and pole position for the A final...
Just as others said, i had to change a little my driving style, because this diff needs more accuracy in using throttle or it will spin the car out when coming into corners... Instead, with big surprise, on full throttle no rear grip loosing in coming out from corners!!!!

Very good first impressions!!!! more details to come....

PS: Any chance to see 126p spur for this diff??

PHILIP RACED WITH IT LAST NIGHT:D

2012.02.05, 12:42 PM
Out of curiosity, I purchased a 43t gear diff yesterday to try to put through some tests. Swapped the spur out for 51t, which was quite easy. I also replaced the delrin adjustment nut with a Qteq nut. I feel that the delrin nut on the normal ball diff is the biggest drawback to the PN diff for me, so I didnt want to take any chances. I used a drop of lube on each spider gear, and gave it a spin. I was impressed by the smoothness.

I put it in a 70t car that I had been working on, gave it a few laps and it felt much more aggressive into the corners, but pushed out. I felt that tire wear increased considerably. I then pulled the diff and gave it to a buddy to use for racing, he liked it, but also noticed more tire wear, his tire wear was nearly double the rate of with a ball diff. We run on carpet with 7d ATM Silicon tires, so it may be a little different on RCP.

In the end, I dont know if it is good for the long runs, but should be good for low power short runs.

Another friend tried one in our Skinny class, and due to the fact that we use narrow rear tires in that class, had to replace it with a ball diff since grip was not high enough for the gear diff.

I've used too many different rear tires and motors at this point to comment scientifically on the rear tire wear, but it does look like the gear diff goes through tires faster on RCP. One workaround I'm trying now is to turn down the Throttle Speed (FWD) on the radio, so that when you hit the trigger, the actual signal that is sent to the car is not "instant throttle", but more like "roll on the throttle at rate X". This approximates the slight slip that a ball diff gives, reducing the loads/slip on the tire and thus wear.

For me, the reduced slip should translate to better consistency too since 95% of my mistakes in Mod are due to over-throttling at the corner exit. If this all works out I can have a nice forgiving car on-power without giving up the huge off-power steering and corner speed that the gear diff provides.

It goes through Kyosho 20's rear tires much quicker even at 70T. Lesson to be learn which I found out have to run brand new set per race night since I was all over the place at the end of the night by skimmpy out in trying to run a set for 2 weeks.

so i was messing around today, and decided to put the ball diff back in my mod car... surprisingly my lap times were the same, but as for a feel... i felt that with the gear diff, I can't have a mistake when applying throttle exiting a corner, but it is very forgiving if you over shoot a corner...the ball diff I feel like its more forgiving on the exit, but not in the entry of the corner.

but it can also be due to my horrible set-up....

I'm still playing with it... I like it, but I think it will be finding a new home in my stock car. It feels nice in my mod, but my driving capabilities doesn't handle it well... im good for 5-10 laps w/o a mistake, but when the mistake comes, i am unable to correct/react fast enough

i have been finding my car to be more and more un predictable running this diff. i am in no way being negative as i think it is a great diff, but my stock 70 turn cars have been so fast that i feel it is giving the car to much rip for my driving style. i have been running this diff since the day they were released and loved it from the first time on the track. i have been running it 3 days a week and even ran 2 different cars in our last event both 70 turn with this diff. i find my driving style to be hard on throttle and lately my cars have just been getting harder to drive. my setups and driving style is so close to the edge of being uncontrollable this diff just puts it over the edge. i may have to dumb my cars down a little to be able to drive it the way i have for so long. i since went back to a ball diff and my cars are back to "normal" i haven't given up on this diff i just ned to retune my cars our drive style to it. i still give the diff a big thumbs up:)

I've just had my first couple of runs with this diff. The one really pressing question I have is - how do you all adjust this one? My fingers are too fat and chunky to turn the adjustor while its in place. I'm having to pull the diff half out to adjust it - and I'm not overly thrilled by this. I dont want to use pliers on the adjustor - I suspect it would get chewed up fairly quickly. Do the adjustors made for the ball diffs (eg MR2049C) that have the hole for the allan key fit this diff? Or maybe a thought for an improved replacement part in the future :)

the problem is when pressure was applied to the right side wheel (when making left hand turns) there was a flaw in the design that would apply to much pressure to the spider gears and cause binding... with the pn design of the open spider gears along with the bearing placement this is no longer an issue.

Are there instructions somewhere as to properly adjust this diff?

I am having some mixed results, if I adjust loose enough for the diff to feel smooth like a ball diff the gears inside will skip which I assume will destroy them within one run.
If I adjust for no internal gear slip and adjust the right rear wheel nut just tight enough to take play out of the wheel the diff does not feel like a ball diff and has a internal friction to it. But on the track all seems fine with my turning handling and drives fine I think?

I think this is one reason why my tire life is cut in half but I'm not sure if the handling within the turn is worth the tire life issue....
(just a side note about this diff; with a 70T I can use the tires until very thin, but with a 50T motor once the tread is lost on the 6d rear tires its over for good handling, well without major throttle touch control which is tiresome IMO.... I like the floor it then coast style of driving...lol )

Um... not sure what you're doing but that is not supposed to happen. You want to tighten on the wheel first, then make your diff adjustment till the gear diff is at least as loose as the ball diff -- my gear diff freewheels for far longer than my ball diffs, due to the complete lack of pressure on the internal components. You should then tighten the diff back up to ball diff levels for easier handling. If your gears are skipping, that is much too loose, and if it's that loose but doesn't freewheel better than a ball diff, you've got some cleaning to do I think.

If you have a brand new diff, my best advice is to not let the tensioning nut back out -- loctite it before you even put the diff on the car. I took out the O-ring while I was doing so, so my nut has not backed out in the almost a year (...wow :eek:) that I've been running the gear diff. The gears in the diff need the correct mesh to work correctly after all, too tight and you grind, too loose and you overload the weakest, outside edges of the teeth. There is honestly only a very narrow setup window in terms of adjusting the diff, you just need to get it right and mesh the teeth properly. The actual "LSD" adjustment is done using different greases.

That, btw, is something I will be playing around with this coming season. Finding the right grease to stay on the gears in an OPEN casing diff has not been easy.

i tore down my car to clean it up and freshen it up...put everything back together, reset the gear diff and it never ran. only bad thing i remember happening putting it back together was the little screw that secures the left wheel to the gear diff came out, i located it and reset it all. ran it around the house for all of 1 minute, loosened it a little bit, put it back in the box, took it to the track and i was served a :( face

Looking nice.

Me btw can't get used to this.
I run faster with ball diff.

So it's something you need to get used to.

Just got this, can't wait to test. Is there a F1 version out yet? if so whats the model number?

it's a really fun diff...my plan is to run a ball in my mod car and gear in my diff..i love the instantaneous power from it, but i love the smoothness/consistency of the ball diff

I'm curious. People have been having problems with the gears chewing themselves up. Is it from running it too loose? I've had one for almost a year now and haven't had a problem with it. I like it a little more then a ball diff but it's not as smooth though. More consistent with the gear diff then a ball diff.

That's the biggest user-side error I've seen. It's not impossible for a bad batch to have slipped into stock as well, but I haven't personally seen a bad gear diff at Kenon yet. Hope people get theirs working well, it's all about not letting the gears get too loose and then crashing. That kills 126p gears, no reason why it wouldn't kill the small gear diff teeth as well.

I've been running mine for about a year as well no problems to speak of. Put some threadlock on the adjuster nut so it can loose and your good to go.

i doubt i did, i'm 99% sure if anything i had it a little too tight and i had to back off a little bit because it was spinning out on teh track that night. did maybe half a turn and it just..made noise and didnt move

Tightening the diff: how does it affect handling? Could it help from loosing power from the outer wheel when the inner is lifted? Could you get the same effect when you appl grease to a stock differential?

It will help, yes, but you will also destroy your turn-in steering as the gear diff is not designed to be tightened like that. Personally, I would run a softer T-plate when switching from the ball diff to the gear diff, the increased roll in the rear will keep the inside rear wheel on the ground and you do not lose any steering since the gear diff gives you more.

Just wondering if an F1 version of this Diff will be out soon? :)
